" I thus entered a high sandy plateau, a thickly 

 wooded forest where there are no rivers, but thousands of 

 pools, the greater number of which only contain water 

 after rain, and which I named the ' Sandy Pool Plateau.' 

 Where I crossed, it is 102 miles in width. . . . Here in 

 coming from the south we met with buffaloes, elephants, 

 and rhinoceroses for the first time. ... I found the 

 limits of the Tsetse were from ten to fifteen miles east of 

 the direction which I took."

 visited the Victoria Falls a few seasons ago, gives the 

 following account of the mode of passing the Tsetse-Hy 

 belt on the south bank of the Zambesi about seventy 

 miles above the Falls. 



" Leaving the last halting-place fi-ee from Tsetse in the 

 evening, they travelled all nig) it to avoid the insect, and 

 before morning reached a narrow strip of country free 

 from fly but without water, though there was grass for 

 the oxen. The next night a shorter march brought them 

 to the river in time for the oxen to drink and return back 

 to the spot free from fly before daylight.
